Description

A kind of organic selenium, selenoprotein and selenium peptide selenoaminoacid mixture extracting method
Technical field
The present invention relates to a kind of raw material extracting method more particularly to a kind of organic seleniums, the mixing of selenoprotein selenium peptide selenoaminoacid Object extracting method.
Background technique
Selenium is trace mineral nutrient needed by human.It is thought that selenium is Harmful Trace Elements in the past, but card now It is a kind of indispensable element of human body in fact.Selenium and vitamin E are both antioxidant, also turn out that it draws to protein is lacked The underfed children risen have therapeutic effect, have resistant function to certain possible carcinogens.People is slight or moderate lacks Selenium, sign or symptom are unobvious.The issuable disease of human body selenium deficiency: energy deficiency malnutrition, blood hemolytic anemia, gram Mountain disease, Kaschin-Beck disease, hypertension, ischemic heart disease, cirrhosis, pancreatitis, fibroma, cancer, myomata, not pregnant disease, glycosuria Disease, cataract etc.;The intake of organic selenium has the advantage that in life
(1), removing toxic substances, gas defence, antipollution, remove bodily waste, garbage toxins, can mitigate chemical carcinogen, pesticide and The toxic side effect of cancer object is connect, selenium is natural antidote;
(2), selenium improves red blood cell oxygen carrying capacity, and the hemalbumin of the haemocyte in blood, red blood cell is protected to will not be oxidized, Its oxygen carrying capacity is just strong, solves the problems, such as the cerebral anoxia of brain worker, reduces the fatigue phenomenon of depression;
(3), the advantage with protection eyes, prevention and treatment eye illness and cancer-resisting;
(4), liver is protected, appropriate selenium-supply can finally remove about 90% hepatitis B, and appropriate selenium-supply can play Acceleration of alcohol catabolism, and then protect liver;
(5), it delays senescence, selenium cooperates vitamin E, can play stronger antioxidation, effective delaying cell aging;Also It can safeguard that male reproductive system, selenium are known as gold in males, male reproductive system selenium content accounts for human body selenium content 20%-40%, selenium are important nutrition and the male reproductive system immune function element of Sperm specific enzyme metabolism;
(6), pancreas islet is protected, selenium deficiency can cause the primary lesion of some islet cells synthesis and secretin function, selenium-supply Pancreas islet can be protected;Selenium can manage property hands at the back sufficient edema, allevating angina pectoris, reduce blood pressure.
By experimental studies have found that, the plant organic selenium rate of being absorbed by the body is 20 times of inorganic selenium.Through clinical test: organic Selenium is largely taken in harmless for a long time, and organic selenium can monthly take in 500-1000ug, and inorganic selenium is largely taken in and will be occurred Selenosis.Developed country has not had to nutritional supplement of the simple inorganic salt form as selenium, and the developed countries such as Japan, U.S. are Forbidden adding the inorganic seleniums such as sodium selenite in food.And the domestic biological the technique of extracting about organic selenium is opposite at present It is less, so, a kind of economical rationality, the organic selenium of function admirable, selenoprotein selenium peptide selenoaminoacid mixture extracting method become Entire society's urgent problem to be solved.
Summary of the invention
To solve the above problems, the present invention provides a kind of organic selenium, selenoprotein selenium peptide selenoaminoacid mixture extracting method.
The present invention provides a kind of organic selenium, selenoprotein selenium peptide selenoaminoacid mixture extracting method, comprising the following steps:
1) removal insect pest, withered, disease, inferior fresh selenium-enriched tea leaf and tea tree branch are selected, it will be fresh with pure water Selenium-enriched tea leaf and tea tree branch wash clean, after moisture drains, are made selenium-rich particle;
2) after selenium-rich particle obtained in step (1) being cooled to 16 DEG C -18 DEG C, low speed colloid mill grinding butter, system are then used Obtain selenium-enriched plant sauce;
3) pure water with selenium-enriched plant sauce homogenous quantities is added in selenium-enriched plant sauce obtained in step (2), is put into low temperature 30 minutes are stirred in blender to abundant dissolution, obtain selenium-enriched plant mixed liquor;
4) after with gauze filter to selenium-enriched plant mixed liquor obtained in step (3) filtering, selenium-enriched plant slurry is obtained;
5) cellulase is added in step (4) in selenium-enriched plant obtained slurry and is uniformly mixed, is put into stainless steel barrel After standing 20min, TG enzyme is added in stainless steel barrel, stirring evenly makes 34 DEG C -36 DEG C of constant temperature in bucket, wait react 30 minutes, side For the reaction of stirring side until cellulose sufficiently decomposes, mixture A is made in proteins coagulation;
6) carbodiimides that selenium-enriched plant starches 2/1000ths weight is added made from step (5) in mixture A, makes egg White matter dehydration, is come out Separation of Proteins using molecule bag filter, obtains plant selenoprotein;
7) edible ethanol of equal quality is added in the plant selenoprotein obtained into step (6), makes its full and uniform mixing, Make protein precipitation, obtains sediment A;Separation of Proteins is come by sediment A with molecule bag filter, high-purity can be obtained Plant selenoprotein;
8) after two centesimal sodium bicarbonates being added in plant selenoprotein made from step (7), 2 times of plants are added The pure water of object selenoprotein is completely dissolved plant selenoprotein under alkaline condition, is subsequently added into the thousand of Selenium in Plants albumen quality / tri- alkali proteases are mixed evenly, 32 DEG C -36 DEG C of constant temperature 40 minutes;Until plant selenoprotein digests completely, obtain Obtain mixed liquid B;
9) mixed liquid B in step (8) is heated to 80 DEG C until having selenium peptide and selenoaminoacid to be precipitated completely from mixed liquid B Until, water salt, selenium peptide and selenoaminoacid will be separated with molecule bag filter, and obtain mixture C;
10) mixed liquor C obtained in step (9) is put into 50 minutes in freeze dryer and is lyophilized, be dehydrated to 10%, can be obtained Organic selenium peptide selenium egg amino acid.
Further, the selenium-rich particle is the 1mm particle that production is crushed by double-pole pulverizer.
Further, the quality of the cellulase in the step (5) accounts for thousand points of selenium-enriched plant slurry quality in step (4) Three, the quality of the TG enzyme in the step (5) accounts for 6/1000ths of selenium-enriched plant slurry quality in step (4).
Further, the mixture C is the mixture of water salt, selenium peptide and selenoaminoacid.
Further, the organic selenium peptide selenium egg amino acid in the step (10) is the mixing of selenoprotein and selenomethionine Object.
Beneficial effects of the present invention:
Organic selenium of the invention, selenoprotein selenium peptide selenoaminoacid mixture are mentioned from fresh selenium-enriched tea leaf and tea tree branch It takes, cost of manufacture is cheap, manufacture craft is simple, can produce on a large scale, is suitable for promoting the use of, solves organic in traditional technology The problems such as extraction of selenium is difficult.
